How do I add an error message to the shopping cart screen?
I'm somewhat new to programming in SRM. I'm trying to add some error checking to our shopping cart process. I thought I could add these checks to the BBP_SC_CHANGE method, but I don't want the type of pop-up box that comes up if I just use the 'Message' command. I'd like to have a message come up at the top of the shopping cart screen, similar to the system-standard messages that come up, once you click 'Order' or 'Check'. Should I be using a different method than BBP_SC_CHANGE, and what can I do to get messages to appear on the shopping cart screen?
